I need to know the exact bandwidth used to server each file,
Does Nginx support this feature?

I have a module to measure the bandwidth of based of the accounting_id
set
in the config file.

http {
http_accounting on;

server / {

location /path/to/myfile {
    http_accounting_id  "myfile";

    ....
}

}
}

the result is write to syslog device, you may filter the result in
syslog.

get the code from google code(
http://code.google.com/p/ltliu-ngx-http-accounting-module),
or github(http://github.com/Lax/ngx_http_accounting_module)
